Michele,
This is also a bug in the Borland/CodeGear C++ compiler (see
http://qc.borland.com/wc/qcmain.aspx?d=32959 ). I am trying to get this
report reopened, but in the meantime you will probably have to change
the sqlite3.h file to add a conditional around the sqlite3_index_info
definition, and remove the offending const qualifiers like this:
#ifdef __BORLANDC__
struct sqlite3_index_info {
/* Inputs */
int nConstraint; /* Number of entries in aConstraint */
const struct sqlite3_index_constraint {
int iColumn; /* Column on left-hand side of
constraint */
unsigned char op; /* Constraint operator */
unsigned char usable; /* True if this constraint is usable */
int iTermOffset; /* Used internally - xBestIndex
should ignore */
} *aConstraint; /* Table of WHERE clause constraints */
int nOrderBy;/* Number of terms in the ORDER BY clause */
const struct sqlite3_index_orderby {
int iColumn; /* Column number */
unsigned char desc; /* True for DESC. False for ASC. */
} *aOrderBy; /* The ORDER BY clause */
/* Outputs */
struct sqlite3_index_constraint_usage {
int argvIndex; /* if >0, constraint is part of argv to
xFilter */
unsigned char omit; /* Do not code a test for this
constraint */
} *aConstraintUsage;
int idxNum;/* Number used to identify the index */
char *idxStr; /* String, possibly obtained from
sqlite3_malloc */
int needToFreeIdxStr; /* Free idxStr using sqlite3_free() if
true */
int orderByConsumed; /* True if output is already ordered */
double estimatedCost; /* Estimated cost of using this index */
};
#else
struct sqlite3_index_info {
/* Inputs */
const int nConstraint; /* Number of entries in aConstraint */
const struct sqlite3_index_constraint {
int iColumn; /* Column on left-hand side of
constraint */
unsigned char op; /* Constraint operator */
unsigned char usable; /* True if this constraint is usable */
int iTermOffset; /* Used internally - xBestIndex
should ignore */
} *const aConstraint; /* Table of WHERE clause constraints */
const int nOrderBy;/* Number of terms in the ORDER BY
clause */
const struct sqlite3_index_orderby {
int iColumn; /* Column number */
unsigned char desc; /* True for DESC. False for ASC. */
} *const aOrderBy; /* The ORDER BY clause */
/* Outputs */
struct sqlite3_index_constraint_usage {
int argvIndex; /* if >0, constraint is part of argv to
xFilter */
unsigned char omit; /* Do not code a test for this

} *const aConstraintUsage;
int idxNum;/* Number used to identify the index */
char *idxStr; /* String, possibly obtained from

int needToFreeIdxStr; /* Free idxStr using sqlite3_free() if
true */
int orderByConsumed; /* True if output is already ordered */
double estimatedCost; /* Estimated cost of using this index */
};
#endif
Be advised, that after I do this I get a similar unresolved external
error for _sqlite3_libversion. I'm trying to see what might be causing
this, but the generated sqlite3.lib file looks OK on first inspection.

On 12/12/06, Michele Santucci <[EMAIL PROTECTED]> wrote: this's a run-time error not a linker error. It sounds like a load time error. If that's the case, and it is the Windows loader, then your import tool did not do translation correctly: it's looking for the literal name "_sqlite3_open" in the DLL exports. Such a name does not exist. The Microsoft import library format sets up name translations, where the underscore is supplied for the usual linking mechanisms, but the linker is also instructed to place the undecorated name in the dependency table. You want to have your tool do the same thing. Failing that, look for a way to have the compiler not apply decorations to dllimport function declarations. One of those must be supported, since it would be required to use Windows API functions (stdcall has a decoration format of its own). Failing that, give up on the stock dll and build your own, or compile sqlite directly into your project :) - To unsubscribe, send email to [EMAIL PROTECTED] -
